Marietta Square spends most of the year as a well kept secret among the people who live within walking distance of it, and then Labor Day weekend arrives and the rest of metro Atlanta remembers it exists. The stretch from Monday, August 31 through Tuesday, September 8, 2026 is one of the fullest nine day runs on the local calendar: a fine art festival that takes over the park, a long running Saturday market, a First Friday gallery stroll, and a museum exhibit worth an unhurried hour. Here is how to plan it around Marietta Square and the Cobb County blocks surrounding it.
40th Annual Marietta Art in the Park
Why It Stands Out
Art in the Park is the only juried fine art festival in Cobb County, and 2026 marks its fortieth year. Presented by the Marietta Business Association, it fills Glover Park at 50 N. Park Square with painters, sculptors, printmakers, ceramicists and jewelers for three days, Saturday, September 5 through Monday, September 7, from 10am to 5pm each day. Attendance runs past 55,000 across the weekend. The jurying is what separates it from a craft fair: the work on the lawn is the kind you hang and keep, not the kind you buy and forget. Details are at artparkmarietta.com.
Timing and Planning
Go early on Saturday or wait for Monday. The 10am hour on opening day is the last quiet window before the lawn fills, and Labor Day Monday itself tends to draw a lighter, slower crowd once the weekend visitors have gone home. Street parking around the Square disappears by mid morning, so aim for the decks and lots a block or two off Park Square and accept the short walk. Bring cash as a backup, and if you are buying anything framed, park somewhere you can carry it to without crossing the whole festival.
Best For
Couples building a collection, newcomers who want a fast read on the local creative scene, and anyone furnishing a house and tired of catalog art. Families do fine here too, though strollers get awkward in the tent aisles once the afternoon crowd thickens. Pair it with lunch at one of the restaurants ringing the Square and the day fills itself.
Marietta Square Farmers Market
What to Expect
Saturday, September 5, from 9am to noon at 41 Mill Street, a half block off the Square. The market averages around 64 vendors and runs year round, which makes it the single most dependable thing on this list. Early September is a generous moment in Georgia: heirloom tomatoes still coming in, peppers and squash at their peak, plus cut flowers, local honey, herbal soaps, whole grain breads, and jams and preserves. Live plants too, if your porch containers need a refresh before fall.
Insider Tip
This particular Saturday overlaps with the first day of Art in the Park, so the Square will be busier at 9am than on a normal weekend. Treat that as a feature. Shop the market first, walk your bags back to the car, then return to the festival on foot with the morning already banked. Vendors selling produce and flowers tend to sell through their best stock in the first ninety minutes, so a 9am arrival is meaningfully different from a 10:30 one.
Neighborhood Angle
The market is the clearest expression of what makes the Square work as a place to live: a walkable core where a weekly ritual happens on foot, followed by coffee and a conversation with someone you recognize. Residents of the surrounding blocks treat it as an extension of the kitchen, and it is the easiest low commitment introduction to the area for anyone still deciding where in Cobb County to land.
Marietta Square Art Walk
Why It Stands Out
On Friday, September 4, from 5pm to 9pm, the Square hosts its First Friday Art Walk, a free self guided tour of galleries, studios and participating shops centered on 50 N Park Sq NE. Local artists set up throughout the district, storefronts stay open late, and the whole thing runs on its own rhythm: you wander, you double back, you stop when something holds you. The series has been going long enough to have its own regulars, and 2026 marks its twentieth anniversary.
Best For
Friend groups and couples who want an evening with structure but no schedule. Because there is no ticket and no start time to make, it absorbs a late arrival gracefully. It is also an unusually good first date format, since walking gives you something to talk about and the galleries do half the work.
Timing and Planning
Book a dinner reservation for 7:30 or later and use the first two hours for the walk. That sequencing matters this particular Friday, because Art in the Park crews will be staging in Glover Park for the next morning and restaurants around the Square will already be seeing early festival traffic. Park once, on a side street north or east of the Square, and stay on foot for the rest of the night.
Marietta History Center at 30
What to Expect
The Marietta History Center sits at 1 Depot Street NE, a short walk from Glover Park in the old freight depot, and its anniversary exhibit runs from January 31 into late fall 2026. Galleries are open Tuesday through Saturday, 10am to 4pm, which puts September 1 through 5 and September 8 inside this window. The exhibit traces three decades of the institution itself, which turns out to be a sideways way of telling the story of the city: what was collected, what was saved, and what nearly was not. Admission is $10 for adults and $7 for students and seniors, with members, children under five and military admitted free. Listings are on the Visit Marietta calendar.
Insider Tip
Use it as the Tuesday move. September 1 and September 8 are the quietest days on this list, and a weekday morning at the History Center is close to a private viewing. It also pairs well with the festival weekend as a recovery activity: air conditioning, low volume, and an hour of context that makes the buildings around the Square legible on your next walk through them.
Neighborhood Angle
Nothing explains the architecture around Marietta Square faster than an hour in the depot. The rail line, the courthouse blocks, the shift from a working freight yard to a dining and gallery district: it all connects, and it changes how the surrounding streets read afterward.
Event Q&A
What is the single best day to be on the Square during this window?
Saturday, September 5. The farmers market opens at 9am, Art in the Park opens at 10am, and both are within a few minutes of each other on foot. Arrive by 9, park once, and you have a full morning and afternoon without moving the car. Monday, September 7 is the calmer alternative for the festival alone.
How difficult is parking during Labor Day weekend?
Tight, and it tightens fast. Street spaces directly on Park Square are effectively gone by mid morning Saturday and Sunday. The workable strategy is to target a deck or lot a few blocks out, arrive before 10am, and stay parked. Anyone coming in the afternoon should plan on a longer walk in.
Are any of these free?
The First Friday Art Walk is free and self guided, and the farmers market costs nothing to browse. The History Center charges admission at the rates listed above. For Art in the Park, check the festival site for current entry details rather than assuming.
What works best with children in tow?
The farmers market, easily, and then the History Center. Art in the Park is family friendly but the tent aisles get congested after noon, so an early arrival makes a real difference with a stroller. The Art Walk skews toward an adult evening, though earlier in the 5pm hour is manageable.
Is one evening enough, or should this be a full weekend?
Friday evening on the Square stands on its own as a complete outing. The festival rewards a longer visit, though, and stacking Friday night with Saturday morning gives you the Square in both of its moods. The Agency Atlanta follows how these neighborhoods actually live from one weekend to the next, and this stretch of the calendar is a good one to see firsthand.
